VID/PID是必须申请的吗？

LeoRuan

1. 基于STM32的MCU上开发一个USB的设备，请问是否需要去USB-IF申请VID和PID？
2. 为这个设备开发一个Windows驱动程序时，INF文件的作用是什么？跟上面申请的VID/PID有什么联系？
3. Windows7上 WHQL是必须的吗？

1、申请要钱的，要几大千美元，如果不是大公司，不用申请，用芯片商的ID吧
2、有关INF的作用，请看USB开源项目EASY USB 51 PROGRAMER PLUS里的“USB厂商自定义设备类”章节相关内容，里面有介绍。
3、WHQL认证是全球最大的个人操作系统软件生产商的微软公司为了保证系统的稳定性与兼容性而推出的一项基准认证制度，不是非要取得这个认证才能连接到运行了windows系统的电脑，在WIN7及以下操作系统中不是必须的，但到了WIN8，由于必须要经过认证取得数据签名后才能安装驱动程序，所以那此不是标准设备类，不用微软提供的驱动的话就得进行认证了。

上面的数据不全，没有看到请求设备描述符的部分，这部分在不停地SET FEATURE和GET STATUS，设备根本没有枚举成功。
